Analysis Test and Optimization of Oil Absorption Performance of Long Pipeline Hydraulic Pump

In order to solve the problem of insufficient hydraulic absorption and leakage of hydraulic pump under long pipeline conditions, the long pipeline suction pipe of hydraulic lifting and lubrication system of a tractor is used as the object, and its oil absorption performance is carried out. Comparative analysis and experimental studies before and after structural improvement optimization. The theoretical calculation is carried out by the theory of pressure loss of fluid mechanics. The simulation is carried out by using 3D software such as Pro/E, ICEM-CFD and Fluent, and test the prototype of the original machine and structural improvement. The main factors affecting the oil absorption performance of the hydraulic pump under long pipeline conditions are the pressure loss of the suction pipeline, the filter pressure loss of the filter and the relative position pressure loss of the fuel tank and the hydraulic pump; the test indicates the structural optimization of the oil pipeline of the long pipeline It is innovative and popular in terms of oil absorption performance improvement, reliability and aesthetics; pressure loss data for theoretical calculation, simulation, and test are consistent over the tolerances.
